“…Digital watermarking techniques are introduced to protect digital multimedia content mostly in the sense of authorship protection, authentication or integrity protection [1][2][3]. Generally, watermarking is implemented by inserting a certain sequence (watermark) to the existing digital content.…”

“…The sequence is embedded in spatial or some transformation domain like the discrete cosine transform (DCT) [1], [3], the discrete wavelet transform (DWT) [1], [4], time-frequency or space/spatial-frequency transformation [1], [2], [5]. When considering invisible and robust watermarking scenario, it has been shown that the transform domain based approaches overcome the performance of time or spatial domain techniques.…”

The watermark detection procedure for images corrupted by impulsive noise is proposed. The procedure is based on the compressive sensing (CS) method for the reconstruction of corrupted pixels. It is shown that the proposed procedure can extract watermark with a moderate impulsive noise level. It is well known that most of the images are approximately sparse in the 2D DCT domain. Moreover, we can force sparsity in the watermarking procedure and obtain almost strictly sparse image as a desirable input to the CS based reconstruction algorithms. Compared to the state-of-the-art methods for impulse noise removal, the proposed solution provides much better performance in watermark extraction.

This paper illustrates how a complex application, the Data Acquisition and Space Shuttle Launch Control System at NASA Kennedy Space Center, which requires both intensive communications and high processing power, can be mapped into an advanced open system architecture. This is achieved by employing a symmetric, tightly-coupled multiprocessor system which includes a high bandwidth common memory bus, an efficient in t e rr up t distribution se he me, d ed ic a t e d high-performance I I O processors, and runs a multiprocessor real-time UNIX operating system.
